How to convert AAC to MP3
1. Upload your AAC or M4A file
Drag a file onto the box above, or click to browse. Both .aac and .m4a files are accepted — they both contain AAC audio.
2. Choose MP3 and a bitrate
MP3 is already selected as the output. Pick a bitrate — 320 kbps for best quality, 192 or 128 kbps for smaller files.
3. Convert & download
Click Convert & Download. Your MP3 is created and downloaded automatically, ready to play anywhere.
.aac and .m4a are both AAC
If your file ends in .m4a, it's still AAC audio — .m4a is just the MPEG-4 container Apple uses around the AAC codec. This tool accepts both, so you don't need to rename anything. To understand the difference, see AAC vs M4A.
Which bitrate should I choose?
Both AAC and MP3 are lossy formats, so converting adds a small amount of loss. Choosing a high bitrate keeps that inaudible: 320 kbps is transparent for virtually all listeners, 192 kbps is a good balance of quality and size, and 128 kbps makes the smallest files.
